The host was great and communicative. The unit was clean and comforting while the location also being great. We felt like we thoroughly enjoyed Bangkok, however, there were concerns while passing through common areas of the condo building.
That said, expect to see large, very obvious, 7 ft tall signs saying Daily/Weekly rentals to travelers is illegal in the condo building. There was a woman at the office of the condo building that took photos of us as we asked to get help on how to get to our unit. Our friend, a local Thai friend, was also concerned that we would be kicked out and lose our stay after speaking with the woman.
All in all, nothing happened. We stayed the full week and enjoyed Bangkok. It was a bit stressful walking through common areas as we made large efforts in avoiding other people, even if it seemed obvious that some of those other people are Airbnb guests. Please do your research.
